NethServer release 7.6.1810 (final)
Not sure which module
I have successfully migrated from Zentyal 5 to Nethserver.
All is working fine except for the Reports->Graphs page.
This page remains blank, no errors are shown.
I have found no relevant information in the logs in /var/log.
The only entries shown are the successful GET in the httpd log.
./httpd-admin/access_log:4798:ip_removed - - [30/May/2019:11:36:09 +0200] “GET /en-US/CGP HTTP/1.1” 200 9159
How can I further investigate and fix the issue ?
